Florida epidemiologists have ruled out travel as a possible source for two Zika infections — one in Miami-Dade and one in Broward — suspected of being the nation’s first cases transmitted by local mosquitoes, State Surgeon General Celeste Philip said Tuesday during a meeting with Gov. Rick Scott and health officials.

“The individuals do not have travel history themselves,” Philip said at the Broward health department in Fort Lauderdale. “That’s the only mode that we feel pretty certain has been ruled out.”

As state health officials reported six new Zika infections on Tuesday, raising the statewide total to 364 people affected this year, Philip asked for patience while Florida epidemiologists undertake the labor-intensive investigation.

With an abundant, almost year-round population of Aedes aegypti mosquitoes (the bloodsuckers capable of transmitting the illness) and a high volume of travelers from Zika-prone countries, the Sunshine State is especially vulnerable to an outbreak. None of the cases in Florida and elsewhere in the continental U.S. have been transmitted locally by mosquitoes and only a handful are confirmed transmissions by sex.

Deputy Town Manager Jay Boodheshwar has said the most important issue at this stage of the Zika Virus outbreak is preventing the spread of mosquitos. The Town, sponsored by the Civic Association and Citizens Association, is holding a Forum on August 3rd in Town Hall.

Dr. Robert Jacobson, a retired hematologist/oncologist, was raised and attended medical school in South Africa, where mosquito-borne illnesses were common and protective measures had to be taken.

With the mosquito-borne Zika virus becoming a worldwide concern, Dr. Jacobson urges residents to take precautions when going outside. He emphasizes the importance of screens on all windows and any outside porches or patio areas.
